Where is the Camshaft Position Sensor 1 located on the Teana?

The Camshaft Position Sensor 1 on the Teana is located next to the flywheel. The camshaft position sensor is a sensing device whose function is to collect the position signal of the camshaft and input it into the electronic control unit to determine the ignition timing and fuel injection timing. Taking the 2021 Teana as an example, it belongs to the mid-size sedan category with body dimensions of: length 4901mm, width 1850mm, height 1450mm, and a wheelbase of 2825mm. The 2021 Teana is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 156ps, a maximum power of 115kw, a maximum torque of 197nm, and is paired with a continuously variable transmission.
I recall that the Camshaft Position Sensor 1 on the Teana is generally located near the top of the engine cylinder head, specifically on the side close to the intake manifold, adjacent to the end of the camshaft. When I worked on my own car, I encountered this too. After removing the engine cover and tracing along the front of the engine, the sensor is usually a small square box with a wiring connector, somewhat tucked away but not hard to spot—though sometimes the intake pipe can obstruct the view slightly. The installation angle is crucial, as even a slight misalignment might trigger false data readings, causing the check engine light to come on or starting difficulties. That's why I always advise cleaning any oil residue around it before inspection. Replacing the part isn't difficult, but it's essential to use genuine OEM parts for compatibility. If you're doing it yourself, keep a wrench and electrical tape handy, and avoid forcefully bending the wiring harness to prevent wire breakage. Given the compact layout inside the engine bay, regularly using an OBD scanner to read trouble codes can help prevent issues from escalating.
I've worked on numerous Teana models, and the Camshaft Position Sensor 1 is indeed designed above the engine cover near the end of the camshaft, commonly located close to the valve cover. Though small in size, it plays a crucial role in detecting the camshaft's rotation angle and sending signals to the ECU to control ignition timing. Incorrect positioning can affect power output and fuel consumption. During inspection, ensure the connector is secure, and when unplugging, gently push to avoid damaging the pins. Sensor failure is a common issue that may cause idle shaking or weak acceleration. It's recommended to use a multimeter to check if the resistance falls within the normal range (typically between 500-1500 ohms). Regular maintenance should include checking for wiring harness aging, as dust accumulation can also cause signal interference.
